If your palms sweat when you’re nervous, you can blame evolution.
The inside of your hands have more sweat glands than any other part of your body.
This is because tens of thousands of years ago, when our primal ancestors were threatened by savage carnivores, the quickest exit was the nearest tree.
Stress caused their palms to sweat, and the moisture gave them a better grip on the branches and vines they were climbing.
How do you prevent sweaty palms? Calm down.
